Human hair has a natural tendency to grow, fall out and re-grow. It grows for about six years, falls out, and new strands of hair start growing. If this cycle is broken, a person will suffer hair loss. Hair problems can cause damage to your looks and your confidence. In this article, I will describe some of the diseases of the scalp and hair that will result in hair loss. Read carefully to know about the diseases and methods about how to avoid them or cure them.
Alopecia Areata: Alopecia Areata is a skin condition in which the body develops antibodies against hair follicles. White blood cells attack the hair follicles, leading to hair loss and can lead to total baldness as the hair cannot re-grow. At first small patches are visible, but the disease can spread to all parts of the body. If you have been suffering from hair loss, take the advice of a doctor as it could be alopecia areata. It can be treated with medicated creams and shampoos. Steroid creams and injections can also be prescribed. Minoxidil solution, medicated shampoos or laser therapy are used to fight this condition.
Alopecia Universalis: The condition is like Alopecia Areata but hair loss occurs in all parts of the body is known as Alopecia universalis and is thus more severe. It can be treated by medications as the hair follicles remain alive. Treatments of steroid injection, medications and ultraviolet light (UV) therapy are known to help.
Androgenic Alopecia: Androgenic alopecia develops when the hair lifecycle is disrupted. The first stage of the hair lifecycle, the growing phase, becomes shorter. The hair follicles become thinner and hair loss results. Treatments include minoxidil, which increases the anagen phase and increases the blood flow to the follicles, thereby preventing them from becoming thin. Other medications like finasteride help fight and rogenetic alopecia.
Telogen Effluvium: Poor nutrition, stress or hormonal imbalance can sometimes cause hair to remain longer in the telogen phase, which is the resting phase. This results in hair thinning and hair fall. If it is not treated, baldness will gradually result. Telogen Effluvium can be corrected by improving the diet. Sometimes it may occur due to eating a new medicine, and the doctor can suggest an alternative.
Tinea Capitis: Bare patches on the scalp are caused by Tinea capitis. It is caused by fungi infections and can affect the scalp, eyebrows and eyelashes. It is a skin condition and is also called scalp ringworm also. Medications are available to treat tinea capitis and to control the fungus causing it. Medicated shampoos containing ketoconazole or selenium sulphide are available and are used to fight the infection.
These are some common hair diseases that people experience. They may be caused by genetic disposition or infections. While male baldness with a receding hair line and baldness is common, women experience thinning of the hair. Other causes of hair loss are pregnancy and delivery, dandruff, stress, illnesses such as thyroid and diabetes, poor nutrition and lice and fungal infestations. They may lead to itching and flaking, and subsequent hair loss. Fortunately, most hair conditions can be treated. Sometimes medications do not work, especially if the cause of hair loss is genetic. In such cases, hair transplants work the best.
